I bought a dirt cheap prebuilt pt2399 ech pcb online for under 12 US bucks shipped from Bulgaria. Neat and tidy pcb with simple hookups for power and in/out points. It's not hardwired yet as I want to tweak a few things but she's fully operational and a hoot to play with.

The trim pots control the delay time and wetness of the effect and it is similar to most of the overpriced delays on the market using the pt2399 chip. I need to read up a bit more on it but adding cv input shouldn't be too much trouble and worth the time. Full sized pots are a must too.

All in all, a great way to experiment with echo without breaking the bank.

phobos added a Cv to Pin 6 of the pt3299:
your "ghetto pcb" looks like it have a very low parts count... (without any op amp)...
...maybe one day you in the moods and paint the schematic to share
i like it simple, this is my version:
btw in my wordl - delay is the most important FX

Thanks for the schematics . That transistor on the tail end of the delay pot on pin 6 is just perfect.

Here's some pics of the pcb I bought. I already replaced the smd 10k resistor (pin 6) and trim pot with a 100ohm resistor and 50k full sized pot. From what I have traced so far, this is a standard echo based right off the pt2399 data sheet. No frills but gets the job done .

yeah some delay really makes everything sounding sweet.
I've tried this "ERSATZ VERBEN"simple reverb/delay and with some tweeking of the pots it sounds great for such a simple build.
That site is an endless well of good stripboard FX designs

it is a bit sensitive about levels of the input though. Does adding some buffer help this?

And a really cool thing is to put a photoresisor on the delay-time-pot for
some wavy seasickness
